There is a fundamental magical difference between anything artificial and anything natural.
In fact, this magical difference is even enshrined in physics in the Copenhagen interpretation of quantum mechanics. The laws of physics are deterministic until human beings get involved at which point they become magically non-deterministic (whatever that means).
It is also enshrined in the Lockean doctrine of "natural rights" which the USA believes in. Negative rights are natural (don't require human action) and positive rights are artificial (do require human action). In the communist doctrine of human rights, there is no distinction.
This magical difference is why watching someone drown to death is okay but drowning them yourself is wrong, as every red-blooded American is taught to believe since true freedom is the freedom to drown.
This magical difference is why 4 to 8 milliSieverts per year of natural radiation is perfectly acceptable. But 0.05 milliSieverts per year due to standing outside of a nuclear plant 24 hours a day, 365 days of the year is totally unacceptable.
So now you know the reason why the actions of quadrillions of natural cosmic rays is unimportant compared to a few dozen artificial beams in the LHC. Obviously the latter are much more threatening to us in magic-magic land.
So if a black hole 'just happens', its okay, but if we make it ourselves: no way!
If it just happens then it's nature's revenge or proof of the sinfulness of humans.
Nature is Mother and God is Father, you know. And they LOVE us even as they beat us. In fact, that's WHY they beat us. Because we deserve it!
Magical thinkers "reason" using magic because they're incapable of using logic. In fact, they're incapable of grasping any abstract concept at all.
Hence why they have to recycle the few concepts they do have. Which invariably turn out not to be abstract like "mortality risk" but rather concrete anthropomorphizations like "mother won't be pleased".
Mother won't be pleased with us making black holes on our own. In fact, mother won't be pleased with us doing anything, being independent like and saying what a murderous fucking bitch she is.
